Subject: [v3 03/21] rsi: fix sdio card reset problem
Date: Thu, 6 Jul 2017 20:07:06 +0530 [thread overview]
Message-ID: <1499351844-2046-4-git-send-email-amitkarwar@gmail.com> (raw)
In-Reply-To: <1499351844-2046-1-git-send-email-amitkarwar@gmail.com>
From: Karun Eagalapati <karun256@gmail.com>
card reset is not working with recent kernels. Using
host->card->ocr instead of host->ocr_avail solved the problem.
